Best AI Tools to Turn Long Videos into Shorts in 2026: 10 Tools Compared

Long videos can contain dozens of great moments, but finding those moments manually can take a lot of time. A podcast, interview, tutorial, livestream, or YouTube video may be an hour long, while only a few parts are perfect for YouTube Shorts, TikTok, or Instagram Reels.

This is where AI can make the process much easier.

An AI tool to turn long videos into shorts can analyze a longer video, identify potentially useful moments, and turn them into shorter clips. Depending on the tool, it can also add captions, reframe the video vertically, remove filler words, and prepare the clips for social media.

I researched several options for this article because I wanted to see what actually makes these tools different. Some focus heavily on automatic clipping, while others give you more editing control after the AI has created the clips.

So instead of simply listing random AI tools, this guide compares 10 options and explains what each one is best suited for.

What Is Long Video to Short Video AI?

Long video to short video AI refers to software that uses artificial intelligence to find useful sections inside longer videos and turn them into shorter, social-media-friendly clips.

For example, instead of watching a one-hour podcast and manually searching for interesting moments, an AI video clip tool can analyze the recording and suggest sections that could work as individual Shorts.

Depending on the platform, the process can include:

• Finding interesting moments
• Creating multiple short clips
• Automatically reframing videos into vertical format
• Adding captions
• Removing filler words or silence
• Creating hooks or titles
• Adjusting clips for social media

The important thing to remember is that AI is helping with the repetitive part of editing. You should still review the final clips before publishing them.

Why Turn Long Videos Into Shorts With AI?

Long-form videos can take a lot of effort to produce. Creating completely new short-form content for every platform can add even more work.

Repurposing solves part of that problem.

One long video can potentially become several pieces of short-form content. A podcast episode, for example, could produce multiple clips instead of being used only once.

This can help creators:

• Save editing time
• Create more content from existing videos
• Reach short-form audiences
• Reuse podcasts and interviews
• Create YouTube Shorts more efficiently
• Prepare content for TikTok and Instagram Reels

The biggest advantage is not that AI creates a perfect Short automatically. The real advantage is that it can make the first stage of finding and preparing clips much faster.

My Experience Researching AI Video Clip Tools

When I started researching long video to short video AI, I expected it to be straightforward.

It wasn’t.

I searched Google using different phrases, including long video to short video AI, turn long videos into shorts AI, and AI video clip tool. I found many platforms offering similar promises, but once I opened them, the features and workflows were quite different.

I also noticed that some results made it difficult to understand what was actually included in the free version. I would open one tool, check its features, go back to Google, and compare it with another.

That experience made one thing clear to me: the tool with the biggest feature list isn’t necessarily the best tool for every creator.

For someone who already works with short-form content, things like captions, vertical framing, clip selection, ease of use, and how much editing is still needed after AI processing matter a lot.

That’s why I decided to compare these tools based on their actual workflow rather than simply calling one of them “the best.”

10 Best AI Tools to Turn Long Videos Into Shorts

1. HeyGen

HeyGen is one of the options worth considering if you want an automated long-to-short workflow.

• Good balance of AI and manual control

• Easy to customize clips

• Captions and text tools

• Large selection of editing features

• Good for final polishing

Pros

• Good for podcasts and interviews

• Long-form recording workflow

• Useful for repurposing content

• Short-form editing features

• Convenient for creators already using Riverside

Cons

• More features than necessary if you only want a simple clip generator

Submagic

Submagic is especially useful for the finishing stage of short-form content, particularly captions and visual styling.

It isn’t necessarily the first tool I’d choose when the only goal is finding clips inside a one-hour video. But once you have a strong clip, tools focused on captions and presentation can make the final Short much more engaging and readable.

Pros

• Strong caption-focused workflow

• Short-form styling

• Useful for adding visual polish

What Should You Look for in an AI Shorts Generator?

Choosing an AI Shorts generator isn’t just about finding the tool that produces the most clips.

Clip Selection

The AI should identify moments that make sense outside the original long video.

A clip can sound interesting inside a podcast but become confusing when removed from its original context.

Captions

Captions are especially important for short-form videos because many people watch social content with sound turned down or off.

Look for tools that let you customize caption style and placement.

Vertical Reframing

A horizontal podcast or YouTube video usually needs to be reformatted for a vertical screen.

Automatic reframing can save a lot of manual work.

Editing Control

Automation is useful, but you should still be able to change the beginning, ending, captions, or framing when necessary.

Free Usage

If you’re specifically searching for long video to short video AI free, don’t stop at the word “free.”

Check whether the free version includes watermarks, limited credits, lower quality, or restricted exports.

Are There Free AI Tools to Turn Long Videos Into Shorts?

Yes. Several platforms offer free plans, free credits, or limited free trials.

For example, OpusClip currently lists a free plan with monthly credits, while Klap offers one free video on its long-video converter. VEED also provides a one-time free use of its Clips feature.

However, free doesn’t necessarily mean unlimited.

If you’re only experimenting, a free option can be enough. If you’re producing Shorts regularly, you may eventually need more credits, higher-quality exports, or additional editing features.

My Final Take

After researching these tools, I don’t think there is one AI video clip tool that is automatically perfect for every creator.

If your main goal is automatically turning long videos into multiple Shorts, tools such as OpusClip, Klap, Vizard, and HeyGen are strong options to explore.

If you want more control after the AI creates the clip, VEED, Descript, Kapwing, or CapCut may fit your workflow better.

And if your content is mainly podcasts or interviews, Riverside and Descript become more interesting choices.

The biggest lesson for me is that AI should make editing easier, not remove your judgment completely.

A tool can find a potentially great moment, but you are still the person who knows whether that moment actually works as a Short.

So before committing to any platform, upload one of your own videos, try the workflow, check the generated clips, and see how much editing you still need to do.

The best long video to short video AI tool isn’t necessarily the one with the most features. It’s the one that saves you time while still giving you Shorts that you would actually want to publish.
